\subsection{Detailed Description}
The {\bf Semaphore\-Lock}{\rm (p.\,\pageref{classost_1_1_semaphore_lock})} class is used to protect a section of code through a semaphore so that only x instances of the member function may execute concurrently.Semaphore automatic locker for protected access. 

A common use is

void func\_\-to\_\-protect() \{ {\bf Semaphore\-Lock}{\rm (p.\,\pageref{classost_1_1_semaphore_lock})} lock(semaphore); ... operation ... \}

NOTE: do not declare variable as \char`\"{}Semaohore\-Lock (semaphore)\char`\"{}, the mutex will be released at statement end.
